Parts of the EN44 and EN88 Actuators.Product DescriptionThis installation instruction describes the steps fordirect-coupled mounting of the EN44 and EN88series non-spring return electronic actuator.Product NumbersEN44 (all versions)EN88 (all versions)Required Tools• 4 mm hex wrench (provided)• 4 mm (5/32 in.) drill bit and drill• Phillips screwdriver• Marker or pencilExpected Installation Time30 minutesInstallation ConventionsWarningCautionPersonal injury or loss of life mayoccur if you do not perform aprocedure as specified.Equipment damage or loss of datamay occur if you do not follow aprocedure as specified.InstructionsNOTE:Warning: Do not open the actuator.Place the actuator on the damper shaft ofthat the front of the actuator is accessible.The label is on the front side.1. Determine whether the damper blades willrotate clockwise or counterclockwise to open.(See Figure 2.)2. If the blades will rotate counterclockwise, slidethe manual override switch to manual and movethe adjustment lever to the right. (See Figure 5.)Return the switch to automatic.0-10V ControlTo mount a (modulating) EN44B and EN88B, set theDual In-line Package (DIP) switches to the requiredpositions.1. To address the DIP switches, raise the tab onthe lower left side of the actuator. (SeeFigure 2). The factory setting is clockwise(middle switch), with a direct-acting feedbacksignal (right switch).2. Close the tab over the DIP switches.3-Position ControlTo mount a (3-position) EN44C and EN88C forcounterclockwise rotation, follow theCounterclockwise Damper Rotation instructionslocated in the Wiring Diagrams section when wiringthe actuator to the controller.129-271 EAI/EN4-1 DEI, Inc.
